Abstract

An interference canceller for canceling narrowband interference from a received broadband signal takes advantage of the fact that the correlation time for the narrowband interference signal will be significantly greater than the correlation time for the desirable broadband signal. The interference canceller operates by creating a replica of the narrowband interference signal in an auxiliary channel and subtracts it from the main channel to cancel the interference. The auxiliary channel has a delay time larger than the correlation time of the desirable broadband signal. In-phase and quadrature versions of the delayed signal are multiplied by respective weights and subtracted from the received signal to produce an interference-reduced signal. The weights are adjusted by an adaptive block to minimize the power in the interference-reduced output signal.
